For me, with the exception of Quadrophenia, and a couple albums by the Kinks in the mid-seventies, it died by 1972. Think about it-
Beatles- grew, matured, and done by 1970 (really 1969) w/ Abby Road.
Stones- Never as good as their peak, Beggars Banquet, Let It Bleed, Get Your Ya-Ya's Out, Sticky Fingers, and Exile on Main Street. All OVER THE TOP, and NOTHING since caught the energy and power. Moments, yeah, but from the first track of the first album mentioned to the last track of the last album, they couldn't be touched. Makes me wonder just how important was Brian Jones and, later, Mick Taylor was to them. Ronnie Wood SHOULD have been a perfect complement to Keith, but I question that their guitar styles were too similar and actually NOT complementary.
Small Faces, FACES- What DID happen to Rod Stewart? That band, from Steve Marriot through Stewart ROCKED. Atlantic Crossing spelled the demise of sloppy, gin-ladened english rock. Oh well.
Quicksilver- Nothing approached HAPPY TRAILS
Traffic- Low Spark was the end. Shootout at the Fantasy Factory was a formula repeat of the aforementioned and paled. Gone after that. Nice little solo career but nothing approaching the early power of this brilliant band.
Grateful Dead- Peaked between 1969-1972. Workingman's Dead, American Beauty, Skull and Roses Live, GARCIA, ACE, and Europe 72. Started down w/ Wake of the Flood in 1973.
Santana- First four albums over the top. Good stuff later, but not from end to end.
Steve Miller Band- egotistical fuck who's first five albums were it. Pop revival in the mid-late seventies, but never the same w/o Boz Scaggs on the first two albums. Brave New World and Your Saving Grace were damn good, and #5 just fine, but after that...
J.A.- Peaked between BAXTER'S and VOLUNTEERS. Kantner kept the energy on BLOWS, but down, down, down... The Jefferson Starship were outstanding live through 1978, but tubed when Marty bailed a second time. DRAGONFLY, RED OCTOPUS, SPITFIRE were superb, but not brilliant. EARTH good but not superb. FREEDOM AT POINT ZERO & MODERN TIMES O.K. even w/o Grace. Dismissive after that.
Kantner knew it too.
Clapton- Derek & the Dominoes was IT. Everything before golden-Cream, Blind Faith, first solo (Eric Clapton), Bonnie & Delaney, and Derek & the Dominoes. Kicked junk, fell into the bottle, and consequently I fell asleep listening to 461 Ocean Blvd. I defy anybody to point to any comparable brilliance by him following the Dominoes.
Fleetwood Mac- Mystery to Me. Once Stevie Nicks & Buckingham walked into the studio and they junked the two guitar approach it went to shit.
The Who- Starting with THE WHO BY NUMBERS it unraveled. Died w/ Moon. Townshend's EMPTY GLASS would have made an EXCELLENT Who album, but he chose not. In any case, it would have only been an upblip on a downslide. Otherwise were talking about a smack ridden, alcoholic paedophile who missed his mate-Keith, and knew it.
CSN- Sorry, one album. Two with Deja Vu, but needed Neil to make it work. I DO like 4 Way Street- a lot. Crosby's first solo over the top. Byrds reunion album good-not great. Stills, first two solo albums and Manassas first album. Nash- huhhhh????
Neil Young- NOW here's an interesting dude. Golden through the WHOLE seventies. Lost in the wilderness in the early-mid eighties, found himself again in the late eighties through RAGGED GLORY. Now aging gracefully.
Put a tear in my eye.
